About this study

Official title: The Effectiveness of Harmonica Playing in Improving Lung Function Among In-home Patients With Chronic Obstructive Pulmonary Disease

Although it has been documented that harmonica playing plays a role in the pulmonary rehabilitation (PR) of patients with chronic obstructive pulmonary disease (COPD), current studies are limited by small sample sizes, uncomprehensive outcome indicators, and short intervention durations. Thus, the investigators aim to compare the harmonica combination group with the basic-PR-care group in terms of improving health outcomes among COPD patients, such as lung function, self-efficacy, quality of life, compliance with training, and emotional distress.

Read the detailed description

Chronic Obstructive Pulmonary Disease (COPD) is an avoidable and treatable condition characterized by chronic respiratory symptoms and airflow obstruction, primarily due to airway and/or alveolar abnormalities from toxic elements. Because of COPD's high prevalence and mortality, its prevention and treatment pose a global public health challenge that needs addressing.

Pulmonary rehabilitation (PR) is considered a cornerstone of COPD management because it effectively improves exercise tolerance, exercise-induced dyspnea, fatigue, and health-related quality of life. Inspiratory muscle training (IMT) plays an important role in PR. Studies suggest that harmonica playing can emulate inspiratory muscle training, enhancing pulmonary function in COPD patients. Additionally, as a music therapy approach, harmonica playing may alleviate the emotional distress often seen in these individuals.

However, existing studies haven't provided robust evidence to support harmonica playing's efficacy in enhancing COPD patients' health outcomes due to limitations like small sample sizes, non-trial study designs, incomplete outcomes, and short intervention durations. It remains unclear whether harmonica playing can improve COPD patients' physiological and psychological health outcomes.

This study's primary aim is to evaluate whether harmonica playing can boost the lung function of COPD patients compared to those only receiving basic PR care in the control group. The secondary aim is to investigate if harmonica playing can enhance other outcomes related to physical and psychological aspects, such as self-efficacy, quality of life, training compliance, and emotional distress.

Methods:

This is a single-center RCT with a low-risk intervention.

Patients who meet the inclusion criteria and do not meet any exclusion criteria will be randomly assigned to either the intervention or control group. The intervention group will receive a harmonica playing program in addition to basic PR care, excluding the pursed-lip breathing exercise, along with routine follow-up. In contrast, the control group will receive basic PR care, which includes the pursed-lip breathing exercise, along with routine follow-up.

Details of the treatments in both groups are provided in the intervention section.

At baseline and six months post-intervention, the investigators will collect clinical evaluations including:

Lung function (Pulmonary function laboratory tests will be performed only at baseline and six months post-intervention) Physical activity Symptoms Quality of life Psychological well-being (focusing on depression and anxiety) Self-efficacy Fatigue Self-reported compliance and satisfaction Outcome measures will be detailed in the subsequent section.

FEV1% predicted is a commonly used outcome indicator in PR and is suitable for sample size estimation. According to results from similar studies, the minimum clinically important difference (MCID) for FEV1% predicted is 4%, with a baseline standard deviation (SD) of 10%. Given a two-tailed significance level of 0.05 and a power of 80%, each group requires a minimum of 99 participants. Accounting for a drop-out rate of 20%, an estimated 248 patients (124 per group) will be enrolled.

Statistical evaluation will be performed using the SPSS 21.0 program. The intention-to-treat (ITT) approach will be adopted for data analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in FEV1 % predicted

    The investigators will assess patients' lung function using a lung function detector to obtain the outcome of FEV1 % predicted.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

Secondary outcomes (13)
  1. Change in individual strength

    The CIS-Fatigue Scale will be used to assess the level of individual fatigue. The total score for the CIS-Fatigue can range from 7 to 56. A higher score indicates a lower level of individual strength.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  2. Change in fatigue

    The FACIT-F scale will be used to assess changes in fatigue. The total score for the FACIT-F scale can range from 0 to 52. A higher score indicates a higher level of fatigue.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  3. Compliance and satisfaction

    A self-designed questionnaire will be utilized, which contains questions about participants' compliance and satisfaction.

    Measured: After 6 months of intervention

  4. Change in self-efficacy

    The Chinese version of the COPD Self-Efficacy Scale for Chronic (CSES) will be employed to evaluate patients' disease self-efficacy. This is a 31-item scale, with responses ranging from 1 (not confident at all) to 5 (very confident). Responses are summed to produce a total score for each participant. Scores can range from 31 to 155, with higher scores indicating greater self-efficacy.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  5. Change in psychological well-being

    The Hospital Anxiety and Depression Scale (HADS) will be used to assess patients' anxiety and depression. Higher scores indicate increased levels of anxiety or depression. Subscale scores of ≥11 are considered indicative of a 'definite case'. Scores of 8 to 10 suggest a 'suspicious case', and scores of 0 to 7 are deemed a 'noncase' for anxiety or depression.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  6. Change in quality of life

    The St. George's Respiratory Questionnaire (SGRQ) will be used to assess patients' quality of life. The total score ranges from 0 to 100. A score of 0 indicates no impairment in quality of life, while a score of 100 denotes maximum impairment. A higher score indicates a poorer quality of life.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  7. Change in symptoms

    The COPD Assessment Test (CAT) will be employed to assess participants' symptom changes. The total score can range from 0 to 40. A higher score on the CAT indicates a more severe impact of COPD on a patient's health status and thus worse outcomes.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  8. Change in level of physical activity

    The 6-minute walk distance, which represents the level of physical activity, will be assessed using a 6-minute walk test. A shorter 6MWD typically indicates poorer exercise tolerance and correlates with more severe disease.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  9. Changes in levels of breathlessness

    The Modified Medical Research Council (mMRC) Dyspnea Scale will be used to gauge participants' level of breathlessness. Scores range from 0 to 4, with a higher score signifying more severe breathlessness.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  10. Changes in clinical control

    The Clinical COPD Questionnaire (CCQ) will be utilized to gauge clinical control in participants. Total scores range from 0 to 6, with a higher CCQ score signifying poorer clinical control and a worse health status.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  11. Social support status

    The Multidimensional Scale of Perceived Social Support (MSPSS) will be used for assess social support. The scores can range from 12 and 84. A higher score indicates greater perceived social support

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  12. Change in inspiratory muscle strength

    The investigators will assess patients' inspirtaory muscle strength using a lung function detector.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention

  13. Change in expiratory muscle strength

    The investigators will assess patients' expiratory muscle strength using a lung function detector.

    Measured: At baseline, after 1 month, after 3 months, and after 6 months of intervention
